resource_size_t may be defined as 32 or 64 bit depending on configuration,
so it cannot be printed using the normal format strings, as gcc correctly
warns:

pinctrl-at91-pio4.c: In function 'atmel_pinctrl_probe':
pinctrl-at91-pio4.c:1003:41: warning: format '%u' expects argument of type 'unsigned int', but argument 5 has type 'resource_size_t {aka long long unsigned int}' [-Wformat=]
   dev_dbg(dev, "bank %i: hwirq=%u\n", i, res->start);

This changes the format string to use the special "%pr" format
string that prints a resource, and changes the arguments so we
the resource structure directly.

v2: don't break ordering of arguments, that part was correct already, unlike
what I said in v1.

I don't see this in linux-next, did the commit get lost accidentally?

No, it's just that I screwed up the next branch so many times and
Stephen has not been able to pull it into linux-next.

Hope it works now...
